The curl is a signed scalar that represents the magnitude of the 2D surface wind downward stress vector field's local anti-clock-wise rotation at a given point; clockwise rotation is thus given as negative curl. The surface called "surface" means the lower boundary of the atmosphere. "Downward" indicates a downward flux of momentum, which accelerates the lower medium along the vector and the upper medium against the vector. The surface downward stress is the wind stress on the surface.
